This tool gives you a macro for the 4 sliders in the master-track groove control. Also a button to navigate to the master track and a checkbox to enable/disable groove. When all the sliders are set to the same percentage in renoise you get standard style drum machine swing. Having one slider to control all four helps to hone in on your ideal swing setting quickly and accurately.
It can be found in the renoise Tools Menu:
Ledger`s Scripts: Groove Control
Or as a renoise shortcut:
Tools: Groove Control
